Abstract
An information processing method, including: generating second luminance profile data by inputting first luminance profile data of a spreading of light when one light source of a backlight device including at least one light source is lit, and adjusting a thin-out spacing according to positions in a luminance distribution based on the first luminance profile data. Values of the first luminance profile data are thinned in the second luminance profile data.
Claims7
An information processing method, comprising:
- inputting first luminance profile data of spreading of light when one light source of a backlight device including at least one light source is lit;
- and
- thinning by reducing a data amount of values of the first luminance profile data with adjustment of a thin-out spacing according to positions in a luminance distribution of the at least one light source based on the first luminance profile data to generate second luminance profile data, wherein
- the luminance distribution based on the first luminance profile data is divided into at least a first region, a second region, and a third region,
- a spatial luminance variation in the first region is larger than a spatial luminance variation in the second region and a spatial luminance variation in the third region,
- the spatial luminance variation in the third region is smaller than the spatial luminance variation in the second region,
- the thinning is not performed in the first region,
- a ratio of a data amount after the thinning in the second region to a data amount before the thinning in the second region is larger than a ratio of a data amount after the thinning in the third region to a data amount before the thinning in the third region.
